BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to managing expiration dated products and more particularly to refrigerator contents management.

2. Description of the Related Art

A refrigerator, commonly referred to as a “fridge” is a kitchen appliance tasked with cooling its contents. Generally, a refrigerator includes a thermally insulated compartment and a heat pump designed to transfer heat from the thermally insulated compartment to the external environment thereby cooling the contents of the compartment to a temperature below ambient. As it is well known, cooling is a popular food storage technique in developed countries and operates to extend the shelf-life of food by decreasing the reproduction rate of bacteria in the food. The refrigerator thus is used to reduce the rate of spoilage of foodstuffs.

The shelf-life of foodstuffs pertains to the date at which it is expected the foodstuffs to become spoiled despite the operation of the refrigerator. To alert the consumer of the expiration date of a particular product, often the packaging or labeling of the product includes a printed indication of the expiration date of the product. However, as the capacity of a refrigerator can be substantial, in many cases the consumer simply forgets to check the expiration dates of different stored foodstuffs in the refrigerator and frequently can be placed in the position of having to discard unconsumed foodstuffs that have exceeded their respective shelf-lives.

Smart home technologies act to avoid the unnecessary waste of foodstuffs. In this regard, basic smart refrigerators can be programmed by the consumer to alert the consumer when a particular product has exceeded its shelf-life. More advanced smart refrigerators can provide for the optical scanning or wireless sensing of the product expiration date directly from information included with the product packaging. Even more advanced smart refrigerators cooperate with smart containers to achieve the automated tracking of food product expiration dates. Of note, smart refrigerators can include embedded computing systems, or smart refrigerators can be conventional refrigerators with coupled computing systems. In the latter instance, a conventional refrigerator can be retrofitted with a computing system to render the conventional refrigerator a smart refrigerator.

Smart food containers are equipped with communicative sensors that can interact with a reader attached to the refrigerator, and connected to a touchscreen. Whenever a container is used and stored in the fridge, the container can be scanned, recognized, and the user can be prompted to enter food information the contents of the container into an associated computer system. Based on food information and refrigerator settings, the software can calculate how long the food will remain edible and keep stock. Of note, smart refrigerators further can be permit remote access to internal data, for example from a mobile device so that when a consumer shops at the grocery store, the consumer can determine in real time food items to purchase based on low stock reports from the smart refrigerator.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art in respect to smart refrigerators and provide a novel and non-obvious method, system and computer program product for shelf life expiration date management for smart refrigerators. In an embodiment of the invention, a method for shelf life expiration date management for smart refrigerators is provided. The method includes identifying a consumer during a point of sale transaction for purchasing different food items by a point of sale computer system, for example by scanning a bar code or reading a magnetic strip of a loyalty program card or reading a radio frequency identification (RFID) dongle. A list of the different food items can be provided to the smart refrigerator from example from storage in the loyalty program card or the RFID dongle, or as transmitted by the point of sale computer system to the smart refrigerator over a computer communications network. Finally, expiration dates can be determined for the food items in the list and stored in the smart refrigerator.

In one aspect of the embodiment, the expiration dates for the food items in the list can be transmitted from the point of sale system to the smart refrigerator. In another aspect of the embodiment, the expiration dates for the food items in the list can be retrieved from a source in the computer communications network from the smart refrigerator. In yet another aspect of the embodiment, the expiration dates can be retrieved from a data store in the smart refrigerator. In any event, once the expiration dates have been stored in the smart refrigerator, the consumer can be alerted when a food item in the smart refrigerator has an expiration date that has lapsed.

In another embodiment of the invention, a smart refrigerator data processing system is provided. The system includes a smart refrigerator. The smart refrigerator includes both a refrigerator and also a host computer with memory and at least one processor. The smart refrigerator is configured for communicative coupling to a point of sale system over a computer communications network and also includes an expiration date client executing in the memory of the host computer. The client includes program code enabled to receive from storage in an identification device such as a loyalty program card or RFID dongle, or from the point of sale system over the computer communications network a list of food items purchased by a consumer at the point of sale system, to determine expiration dates for the food items, and to generate an alert when a food item in the refrigerator has an expiration date that has lapsed. Optionally, the loyalty program card can identify the consumer and specify an address of the host computer of the smart refrigerator.

Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for shelf life expiration date management for smart refrigerators. In accordance with an embodiment of the invention, a smart refrigerator can be provided for a consumer. At checkout in a grocery store, an identification for the consumer can be provided to a point of sale system. For example, the identification can be provided by way of a consumer loyalty magnetic strip card or consumer loyalty RFID dongle. Thereafter, one or more purchased food items by the consumer recorded in the point of sale system can be associated with the consumer in a list and provided to the smart refrigerator either directly through a storage medium into which a list can be stored such as a consumer loyalty magnetic strip card or consumer loyalty RFID dongle, or communicatively over a computer network at an address associated with the consumer and mapped to the identification. Optionally, expiration date information for individual ones of the purchased food items in the list can be provided to the particular one of the smart refrigerators, or the particular one of the smart refrigerators can retrieve the expiration date information for the individual ones of the purchased food items from a network source. Finally, the expiration date information can be used in the particular one of the smart refrigerators to trigger a notification when a food item is about to expire or has expired.

In further illustration, FIG. 1 is a pictorial illustration of a process for shelf life expiration date management for smart refrigerators. As shown in FIG. 1, a consumer can select for purchase multiple different food items 110. A point of sale system 120 can process the purchase of the food items 110. Additionally, an identification device 140 identifying the consumer, for example a loyalty program card or loyalty program RFID dongle, can be scanned by a scanner 130 at the point of sale system 120. Thereafter, a list 150 of the purchased food items 110 can be stored in the identification device 140. Alternatively, the identification of the consumer by the identification device 140 can be used to select a particular smart refrigerator 170 communicatively coupled to the point of sale system 120 over a computer communications network such as the global Internet.

In the former instance, the list 150 of the food items 110 can be provided to the smart refrigerator 170 directly by scanning the identification device 140 in the smart refrigerator 170. In the latter instance, the list 150 of the food items 110 can be provided electronically over the network to the selected smart refrigerator 170. In either circumstance, an expiration date table 180 can be maintained in the selected smart refrigerator 170 for the food items 110 in the list 150 based upon expiration date information for the food items 110 provided by the point of sale system 120, or retrieved by the selected smart refrigerator 170. In this way, the expiration date information for all of the food items 110 purchased can be tracked in a single transaction at the time of purchase of the food items 110.

The process described in connection with FIG. 1 can be implemented in a smart refrigerator data processing system. In yet further illustration, FIG. 2 is a schematic illustration of a smart refrigerator data processing system configured for shelf life expiration date management. The system can include a host computer 210 with memory and at least one processor supporting the execution of a point of sale system 220. The host computer 210 can be configured for communicative coupling to different smart refrigerator computing systems 240 coupled respective refrigerators 270 over a computer communications network 230 such as the global Internet. An expiration date manager 300A can execute in conjunction with the point of sale system 220 and in concert with different expiration data clients 300B disposed in respectively different ones of the smart refrigerator computing systems 240.

In this regard, the expiration data manager 300A can include program code to identify a consumer purchasing food items, and to store a list 260 of the purchased food items by the consumer in an identification device such as a consumer loyalty magnetic strip card or consumer loyalty RFID dongle. Alternatively, the expiration data manager 300A can include program code to select a particular one of the smart refrigerator computing systems 240 corresponding to the identified consumer, and to forward to the particular one of the smart refrigerator computing systems 240 over the network 230 the list 260 of the purchased food items by the consumer. In either circumstance, the expiration date client 300B executing in the memory of the particular one of the smart refrigerator computing systems 240 can receive the list 260 either directly by scanning the identification device, or from over the network 230, and store in an expiration date table 250 the food items in the list and associated expiration dates.

In particular, the associated expiration dates can be provided by the expiration date manager 300A, retrieved from information sources of the network 230, or retrieved locally from a data store of expiration dates mapped to different food items. In any event, thereafter, the particular one of the smart refrigerator computing systems 240 can alert a consumer to an expired product in comparing the records of the expiration date table 250 to a current date. Optionally, when a food item in the list already appears in the expiration date table 250, the expiration date client can prompt the consumer to update whether or not the food item replaces a prior food item thereby requiring only an update of the expiration date.

In even yet further illustration of the operation of the expiration date manager 300A, FIG. 3 is a flow chart illustrating a process for shelf life expiration date management for smart refrigerators. Beginning in block 310, a personal identification card for a consumer can be scanned, for example a bar code in a loyalty card, a magnetic stripe of a loyalty card, or an RFID dongle of the consumer. In block 320, the consumer can be determined from the scanning and, optionally, in block 330 a network address for a corresponding smart refrigerator can be determined based upon the determined consumer. In block 340, a list of food items purchased by the consumer can be loaded and either stored onto the personal identification card for subsequent scanning in the corresponding smart refrigerator, or in the optional circumstance, transmitted to the network address of the smart refrigerator in block 350. In block 360, expiration dates for the different food items can be determined, either before or after providing the list to the smart refrigerator. In this way, with a single transaction at the point of sale, all expiration data for purchased food items can be provided to a smart refrigerator for an identified consumer.
